17 дек 999 г. до нашей эры - Proto-Germanic

Описание:

The Proto-Germanic can be traced back to the region between the Elbe river in modern Germany and southern Sweden some 3,000 years ago. Jacob Grimm pointed out that, over time, certain consonants in the Germanic family of languages have shifted somewhat from the Indo-European base.
Germanic words like the English foot, West Frisian foet, Danish fod, Swedish fot, etc, are in fact related to the Latin ped, Lithuanian peda, Sanskrit pada, etc, due to the shifting of the “p” to “f” and the “d” to “t”. Several other consonants have also shifted (“d” to “t”, “k” to “h”, “t” to “th”, etc)
